GIBSON DEEP FREEZE IS RUNNING BUT EVERYTHING IS...

Question

I PURCHASED THE FREEZER ABOUT 3 YEARS AGO AND HAVE IT OUT IN OUR GARAGE, WE HAD A REAL NICE MINNESOTA COLD SNAP ABOUT TWO WEEKS AGO AND EVER SINCE I COULD HEAR THE FREEZER RUNNING DIFFERENTLY AND WHEN I WENT TO CHECK ON ALL THE FOOD, EVERYTHING WAS STARTING TO THAW. THE FREEZER IS CONSTANTLY RUNNING BUT NOT FREEZING. ANY SUGGESTIONS.
